My WK just rolled over 30k so I'm trying to gather as much information to tackle this myself.

1. Have anyone went to a dealer to do this? I called 1 Local dealer (Bayside Jeep NYC) and they quoted me $1100. Was going to hang up after i heard the 1 Thou...but curious to see what was involved. Heard a bunch of BS things not mentioned in any of the service manuals. Which leads me to #2...

2. Cant find my owner's manual but this is what's involved in the 30k tuneup from WKJEEPS.

I payed about $140 for fluids/oil filter/spark plugs and I payed $100 for the labor.
$240 is nowhere near $1100. Just buy all the required fluids and take it to your mechanic
I changed the spark plugs myself, 15 minute job

I have quadra drive and my tranfer case takes the nv 245/247/249 fluid... Not ATF+4. Better check your transfer case to see if you have the nv 245. Not sure about quadra trac. That dealer is smoking crack... $1100 for 30k tune up... Yet another reason why i will never go to a dealer again for service.
